Laser Barrel
The LaserBarrel is a type of Barrel that simulates continuous beam fire using a LineRenderer. It can apply damage to nearby targets, visually curves the beam, and supports a wind-up time before activation.
Summary
This component:
- Uses a spline-based beam that updates every frame
- Applies damage to the nearest
Hitbox in range - Supports warm-up delay and impact feedback
- Visually displays the laser using
LineRenderer
Fields
| Field | Type | Description |
|---|
damagePoints | int | Amount of damage applied per hit. |
_line | LineRenderer | Visual representation of the beam. |
resolution | int | Number of spline points used for beam smoothness. |
snapRadius | float | Radius used to detect nearby Hitbox targets. |
maxLength | float | Max distance of the laser beam. |
affectedLayer | LayerMask | Defines which layers the beam can affect. |
windUpTime | float | Time (in seconds) before the laser starts firing. |
Events
| Event | Description |
|---|
OnImpact(Vector3) | Invoked every frame with the laser’s impact point. |
OnWindUp | Invoked once when wind-up starts. |
Public Methods
| Method | Description |
|---|
override void StartShooting() | Enables laser beam and starts firing loop. |
override void StopShooting() | Disables laser beam. |
override void Shoot() | Applies damage to the closest target in path. |
override void Prepare(Action callback) | Delays firing based on windUpTime. |
void SetImpactPosition(Transform target) | Moves a target transform to the laser’s hit point. |
Internal Logic
- Uses
Physics.OverlapCapsule to detect targets near the beam path. - Picks the closest valid
Hitbox within the snapRadius. - Uses a
CubicSpline to bend the beam between origin and destination. - Runs a coroutine to refresh the laser’s appearance and hit detection every frame.
Use Cases
- Energy rifles
- Mining lasers
- Continuous fire weapons
- Tactical scanning beams
